According to my invention, heat is stored in one or more heat storage units which :une and arranged that they may be readily removed to the place where the heat is to be utilized. Preferably, instead of having .one large heat storage unit, I provide a sectional device consisting of severai small sections which may be heated from the same source; vI also provideinsulating means so as to conserve Ithe heat in the storage units when they are not being, used for the cooking or other intermittent operation.

In'the drawing, Figure 1 is a transverse section of a heat storagetapparatus according to myinvention; Fig. 2 is a partial'l longitudinal section of the same; Fig. 3 is an elevation partly in section of a range which may constitute means for utilizing the heat contained in the storage sections,

Be it known that I, Hanny Pinon BALL, a i,

drawings are circular disks. The holding member 3, the partitions 10 andthe storage sections 12 are preferably composed of material such as iron or steel, havino high thermal storage Ca acity and high l[thermal conductivity. Eac, of the storage sections 12 has a recess or .depression 13 in the top thereof-and a pin or bar 14 extendingacross the same s0 .that a removing tool such as the tongs 15 shown in Fig. 4 may be inserted to remove lany section desired. Cover 16 is provided for the storage sections and this may be a metal shell conforming to the -shape of the upper portions of the sections and filled with heat insulating material. This ,cover may be equipped with handles 17 for conveniently removing the same.Y vThe storage heater as ayvhole is provided with the cover 18 which, as shown, 'consists of a metal 'shell filled with heat insulating material and provided With the handles 19. Preferably, the shell of cover 18, the conduit 8 and the throat 4 of the Walln 4 are very thin and composed of metal the door 0f the range being removed, 51g; having high .specific heat resistance such as 4 is a detail view Showing a, means [01 yacalorite described in a certain Dempster Patmoving a storage section from the storage @Ht N0-.901,4Q8 heater.

On top of the range is shown a storage sect-ion which may be used for cooking operations such as frying. As shown in the drawing, the storage sections may be made in the shape of a cooking utensil so that the food to be cooked may be put in direct contact therewith.

wood if desired, which may be mounted upon legs 2. Within the box and spaced therefrom is mounted the holding member 3 which also serves as a part of the heat storage means. Suitable supports such as the rods 3 may be provided for the member Inner Walls for the receptacle of which the member 3 forms a bottom plortion may be 'completed by the plates 4 W ich may be of the holding .deviceand as shown in thev As shown in Fig. 5, the partitions 23 of the stationary part 24 of the heatstorage mass may be integral with the rest of that member and of substantially the same size and shape as the heat storage sections. This form is convenient to construct andaffords a large area of contact between the stationary and removable parts ofthe heat storage mass.

ln the operation of my invention heat is supplied by electrical unit 7 and is stored inthe holding member 3, the partitions l1 and the sections 12. W hen it is desired to use one or more of the heating sections for cooking purposes the same may be removed from the storage heater by any suitable means such as tongs l5 and placed in suitable portions of a cooking device such as the range Q0 or in any other place Where the heat which they contain may be utilized.

Various changes may be made in the shapes, relative arrangement and proportions of the parts shown in the drawing without departing from the spirit of my invention, the scope of which is set forth in the. annexed claims.

lVhat I claim as new and desire to secure by Letters Patent ot the United States, is

l. An electric heat storage device comprising a heat insulating receptacle, a heat storage mass therein consisting of a plurality of removable sections having high heat storage capacity and high heat conductivity and electric heating means supported independently of the said sections in goed thermal conductive relation With said heat storage mass.

2. An electric heat storage device comprising a heat insulating receptacle, a heat storage mass therein having high heat storl I l l I J l agecapacityand high heat conductivitf,

said mass including a stationary holder and and said partitions having high heat Stor-- age capacity and high heat conductivity, and electric heating means in good thermal conductive relation with said heat storage mass.

4. An electric heat storage device comprising a heat insulating receptacle, a heat .storage mass located therein and consisting of a plurality of removable sections having high heat storage capacity and high heat conductivity, and electrical means supported independently of said sections for heating the same, said receptacle having a removable cover to allow any desired number of the said sections to be removed.

5. An electric heat storage device consisting of a heat insulating' receptacle, a heat storage mass therein comprising a plurality of removable disk shaped metal sections each supported on end, and electric heating means for the said stcrage mass supported independently of the said sections.

In witness whereof, I have hereunto set my hand this 2nd day of March, 1912.
